Hi Simon,
Thanks for sharing the thread. I really appreciate that.
I would say that by the discussion regarding the post this is a theme of
interest in the community. You and others make some good recommendations
but, maybe it will be nice to have a better documentation or even some
warning triggers over probable pitfalls on the use of C++ in R packages.
Cheers,
FH

Fernando,
there was a pretty big follow-up discussion on R-devel that's worth reading:
https://stat.ethz.ch/pipermail/r-devel/2019-March/077560.html
but I want to point out that people may have misunderstood the recommendation -
if you just use Rcpp (or other means) to get data from R, run some C++ code and
then return results back, it's completely fine and not what the scope of his
post was. It was about mixing R API calls and C++ in ways where you intersperse
C++ allocations with R API calls and/or where you create classes with R API
which is requires a lot more knowledge than people realize.
That said, I think the Rcpp community is the best line forward here, since Rcpp is in a
position to clarify the technical issues and provide tools if need be. For example, just
flagging Rcpp calls that don't call (non-macro) R API and thus are "safe" could
be useful. I think we could use more supportive comments from Rcpp users/developers on
that thread ;) - just my $.02.
Cheers,
Simon

Dear All,
Recently Tomas Kalibera has post on the blog of R developers about the use o
C++ in R packages.
The post can be seem at the following link:
https://developer.r-project.org/Blog/public/2019/03/28/use-of-c---in-packages/
I would like to know your thoughts over that. In summary, he recommend to avoid
C++ in R packages but for me his points are not too clear. Maybe you can help
me to clarify them.
Cheers,
FH
